Flavored nitrous oxide sold in colorful tanks that consumers inhale to get high must be removed from shelves because it is creating a “national health crisis,” a new lawsuit alleges.

Filed by the family of a Florida woman who died after what relatives said was a yearslong addiction to the gas, the lawsuit accuses manufacturers and smoke shops of exploiting a legal loophole that allows them to sell nitrous oxide canisters if they are marketed as a culinary tool, such as for making whipped cream, rather than an inhalant. “These products have caused widespread addiction, death and severe bodily harm,” the suit says
